I had that over the summer (not pregnant). It was so weird and I was so nervous I even went to a neurologist and had a bunch of tests done and they found nothing wrong. I was going through some pretty bad anxiety at that point and have a feeling it may have been from that. I wouldn't worry too much. Mine stopped in a few weeks and I have not had it since

I have the same tingley feeling on my left thigh...just figure the baby laying on a nerve or something. My though has been numb for a while. Dr said nothing to worry about. Your body goes thru so much. Good Luck!!
